Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple delivers exceptional engineering value in demanding industrial environments where corrosion resistance and pressure integrity are critical. The welded construction combined with NPT threading creates a robust connection point that maintains seal integrity under thermal cycling and vibration stresses common in air, gas, oil, steam, and water systems. The galvanized surface treatment provides sacrificial protection against rust and degradation, significantly extending service life in moist or chemically aggressive environments. Engineered to ASME B1.20.1 standards, this nipple ensures precise thread engagement with compatible 125/150 class fittings, reducing installation time and eliminating leakage concerns in pressurized piping networks across industrial plants, processing facilities, and mechanical systems.

Specification Summary & Compliance

This 3/8" NPT Schedule 40 pipe nipple features Class 2A thread tolerances per ASME B1.20.1 specifications, ensuring precise fit with standard NPT fittings. The product complies with ASTM A53 for material composition and ASTM A733 for welded construction standards, guaranteeing consistent quality and performance. With dimensions of 12" length, 0.493" ID, and 43/64" OD, this nipple maintains Schedule 40 wall thickness (0.091") throughout, providing reliable pressure containment for industrial applications requiring compliance with recognized engineering standards.
